Who is the English writer known for novels that examine the morality of colonialism?

Joseph Conrad is the English writer renowned for his novels that deeply explore the morality of colonialism, particularly through his seminal work "Heart of Darkness." This novel portrays the harrowing journey into the Congo River basin, reflecting on the dehumanizing effects of imperialism both on the colonized and the colonizers. Conrad's narratives often highlight the moral ambiguities and the psychological impacts of colonial practices, serving as a critique of European imperialism.

In contrast, while other authors like James Fenimore Cooper, Stephen Crane, and Herman Melville have made significant contributions to American literature and explored themes of adventure and morality, their works do not primarily focus on the moral implications of colonialism in the same profound way that Conrad's do. This focus on the complexities and contradictions of colonial conquest sets Conrad apart as an essential figure in literature addressing these themes.
